Description

Technical Field

[0001] This utility model relates to the field of chemical machinery and equipment technology, and in particular to a modular evaporator that is easy to maintain. Background Technology

[0002] Evaporators are widely used in industries such as chemical, pharmaceutical, and food processing, primarily for concentrating or separating solutions. Typically, evaporation equipment consists of two main parts: a heating chamber and an evaporation separation chamber, connected by pipes to form a circulation path. During actual operation, due to the characteristics of the materials being processed, scale or deposits easily accumulate inside the connecting pipes between the heating and separation chambers. Therefore, regular disassembly, cleaning, and maintenance are necessary to ensure the equipment's heat exchange efficiency and normal operation.

[0003] However, to ensure the sealing and pressure resistance of the connection, existing evaporators typically use flanges and multiple sets of bolts to fix the heating chamber and evaporation separation chamber together, or they are directly welded together. While this traditional connection method meets the requirements for stability, it has significant shortcomings in equipment maintenance: disassembly requires the use of special tools to loosen and remove a large number of bolts, which is cumbersome, time-consuming, and labor-intensive, resulting in excessive downtime for equipment maintenance and increasing the company's maintenance costs; if the connection is welded, disassembly is even more difficult and may even require damage to the pipeline.

[0004] While some quick-connect pipe fittings exist on the market, conventional plug-in structures often lack reliable mechanical locking mechanisms. Under the high temperature, high pressure, and vibration conditions of evaporators, these connections are prone to loosening or even detachment, posing a safety hazard. Furthermore, existing sliding connection structures often fail to achieve effective sealing in critical areas such as guide grooves, easily leading to material leakage. Therefore, designing an evaporator connection structure that ensures both stable connections and reliable sealing while allowing for quick assembly and disassembly for routine maintenance has become a pressing issue in the current technological field.

[0005] Therefore, this invention proposes a modular evaporator that is easy to maintain in order to overcome the shortcomings of the prior art. Utility Model Content

[0006] To overcome the above shortcomings, this utility model provides a modular evaporator that is easy to maintain, aiming to improve the problems of cumbersome disassembly and assembly at the connection points of existing evaporation and separation equipment and the easy occurrence of media leakage at the sliding guide structure.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: a modular evaporator that is easy to maintain, comprising: an evaporation separation chamber, a heating chamber, and a connecting pipe, wherein one end of the connecting pipe is fixedly connected to the evaporation separation chamber, and the other end of the connecting pipe is fixedly connected to the heating chamber; and an installation component disposed inside the connecting pipe and a locking component installed on the wall of the connecting pipe.

[0008] The mounting assembly includes a sliding tube that slides against the inner wall of the connecting tube, the sliding tube being hollow inside and having two through ends; the locking assembly includes a threaded post and a locking block, the threaded post being threadedly connected to the wall of the connecting tube, and the locking block being located inside the connecting tube and rotatably connected to the end of the threaded post near the center of the connecting tube.

[0009] Furthermore, the outer wall of the sliding tube is provided with a slot, and the shape of the locking block is adapted to the shape of the slot; the threaded column and the locking block are engaged by a rotation-driven radial movement, that is, rotating the threaded column can drive the locking block to move radially along the connecting tube and lock into the inside of the slot, thereby fixing the sliding tube inside the connecting tube.

[0010] Preferably, a guide block is fixedly connected to the outer wall of the sliding tube, and a guide groove is formed on the inner wall of the connecting tube. The guide groove extends along the axial direction of the connecting tube, and the guide block is slidably connected inside the guide groove to restrict the circumferential rotation of the sliding tube.

[0011] Preferably, a sealing ring is fitted on the outer wall of the sliding tube, and a sealing block is fixedly connected to the outer wall of the sealing ring. The position of the sealing block and the position of the guide block are on the same straight line in the circumferential direction.

[0012] Preferably, the cross-sectional shape of the sealing block is adapted to the cross-sectional shape of the guide groove, the sealing block is slidably fitted inside the guide groove, and the outer wall of the sealing ring is tightly fitted to the inner wall of the connecting pipe, thereby achieving filling and sealing of the guide groove opening.

[0013] Preferably, the length of the guide groove is greater than the sum of the distances between the guide block and the sealing block along the axial direction of the sliding tube, so as to accommodate both the guide block and the sealing block simultaneously located inside the guide groove.

[0014] Preferably, the outer wall of the sliding tube is further fitted with a sealing ring, which is located between the slot and the opening of the connecting tube. The outer wall of the sealing ring is interference-fitted with the inner wall of the connecting tube to form the first line of sealing.

[0015] Preferably, a rotating knob is fixedly connected to one end of the threaded post located outside the connecting pipe, and the outer surface of the rotating knob is provided with anti-slip texture to facilitate manual operation.

[0016] Preferably, the locking components are evenly distributed in several groups along the circumference of the connecting tube, and the opening position of the slot on the sliding tube corresponds one-to-one with the distribution position of the locking components, so as to achieve multi-point synchronous and stable locking.

[0017] This utility model has the following beneficial effects:

[0018] 1. This utility model solves the problem that the evaporation separation chamber and heating chamber in existing evaporator equipment are usually fixed by flanges with multiple bolts or welded, which leads to cumbersome disassembly and maintenance and long time consumption. It achieves the effect of unlocking and pulling out the sliding tube by simply turning the knob, realizing the rapid separation of the evaporation separation chamber and heating chamber and modular independent maintenance, which significantly reduces the difficulty of maintenance and shortens the downtime.

[0019] 2. This utility model solves the technical problem that the guide groove in conventional sliding connection structures cannot be effectively sealed due to structural gaps, which easily become fluid leakage channels, by adding a sealing block that matches the shape of the guide groove to the outer wall of the sealing ring. It achieves the effect of using the guide groove to achieve precise guidance while using the sealing block to completely fill and block the groove space of the guide groove, thus building an all-round leak-proof barrier without dead angles, and significantly improving the sealing performance of the equipment under high pressure or vacuum conditions.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Reference Figures 1-5 The present invention provides an embodiment of a modular evaporator that is easy to maintain, comprising an evaporation separation chamber 1 and a connecting pipe 4 fixedly connected to one end of the evaporation separation chamber 1. The end of the connecting pipe 4 away from the evaporation separation chamber 1 is fixedly connected to a heating chamber 5. The connecting pipe 4 serves as an intermediate fluid channel connecting the evaporation separation chamber 1 and the heating chamber 5. An installation component 2 for quick docking and sealing is provided inside the connecting pipe 4. At the same time, a locking component 3 for positioning and locking the installation component 2 is installed on the pipe wall of the connecting pipe 4.

[0029] Specifically, the installation component 2 includes a sliding tube 201 that slides into the inner wall of the connecting tube 4. The sliding tube 201 has a hollow, cylindrical structure with both ends open. The outer diameter of the sliding tube 201 is matched with the inner diameter of the connecting tube 4 to allow the sliding tube 201 to move axially back and forth inside the connecting tube 4, thereby realizing the docking or separation between the evaporation separation chamber 1 and the heating chamber 5. To ensure the connection is stable, the locking component 3 includes a threaded post 302 and a locking block 303. The threaded post 302 passes through and is threaded to the wall of the connecting tube 4. A rotating knob 301 is fixedly connected to one end of the threaded post 302 located outside the connecting tube 4. The outer surface of the rotating knob 301 is provided with anti-slip texture to increase the operating friction. The end of the threaded post 302 located inside the connecting tube 4 is connected to the locking block 303.

[0030] It should be noted that the locking block 303 is located inside the connecting pipe 4 and is rotatably connected to the end of the threaded column 302 near the center of the connecting pipe 4. That is, when the threaded column 302 rotates, it can push the locking block 303 to move radially along the connecting pipe 4, but the locking block 303 itself does not rotate with the threaded column 302. Correspondingly, the outer wall of the sliding pipe 201 is provided with a locking groove 304. The shape of the locking block 303 is adapted to the shape of the locking groove 304. When the sliding pipe 201 is inserted into the predetermined position, the locking groove 304 is exactly located on the moving path of the locking block 303. By rotating the knob 301, the threaded column 302 is rotated and fed, thereby driving the locking block 303 to be embedded in the locking groove 304 radially along the connecting pipe 4, so as to achieve axial locking of the sliding pipe 201 relative to the connecting pipe 4.

[0031] In addition, in order to ensure force balance, the locking components 3 are evenly distributed in several groups along the circumference of the connecting tube 4, such as two or three groups symmetrically distributed. Correspondingly, the opening position of the slot 304 on the sliding tube 201 corresponds one-to-one with the distribution position of the locking components 3 to ensure multi-point synchronous locking.

[0032] A guide block 202 is fixedly connected to the outer wall of the sliding tube 201. The guide block 202 has a regular geometric columnar structure. The guide block 202 protrudes outward along the radial direction of the sliding tube 201 and extends along the axial direction of the sliding tube 201. The guide block 202 is welded or integrally formed on the outer surface of the sliding tube 201. The function of the guide block 202 is to establish a unique motion trajectory for the movement of the sliding tube 201 inside the connecting tube 4 and to restrict the circumferential rotation of the sliding tube 201. Meanwhile, a guide groove 203 is correspondingly provided on the inner wall of the connecting tube 4. The cross-sectional shape of the guide groove 203 is adapted to the cross-sectional shape of the guide block 202. The guide groove 203 extends along the axial direction of the connecting tube 4 and the length of the guide groove 203 is greater than or equal to the insertion stroke of the sliding tube 201. In the assembled state, the guide block 202 on the sliding tube 201 is embedded and slidably fitted in the guide groove 203 on the inner wall of the connecting tube 4. This linear guiding structure of the guide block 202 and the guide groove 203 ensures that the sliding tube 201 maintains a fixed angle posture during the insertion of the connecting tube 4. This ensures that when the sliding tube 201 moves to the predetermined depth, the slot 304 on the sliding tube 201 can automatically and accurately align with the slot 303 on the connecting tube 4, avoiding the situation where the locking component 3 cannot lock due to angle deviation.

[0033] As a preferred embodiment, in order to solve the technical problem that the guide groove 203 in the conventional sliding connection structure is prone to becoming a fluid leakage channel, a sealing ring 205 is sleeved on the outer wall of the sliding tube 201, and a sealing block 206 is fixedly connected to the outer wall of the sealing ring 205. The position of the sealing block 206 in the circumferential direction of the sliding tube 201 is on the same straight line as the position of the guide block 202. The cross-sectional shape of the sealing block 206 is completely consistent with the cross-sectional shape of the guide groove 203. When the sliding tube 201 is inserted into the connecting tube 4, the outer wall of the sealing ring 205 fits tightly with the inner wall of the connecting tube 4 to achieve circumferential sealing. At the same time, the sealing block 206 slides and fits inside the guide groove 203 to fill and seal the groove space of the guide groove 203, thereby constructing an all-round leakage prevention barrier.

[0034] To ensure that the guiding and sealing functions do not interfere with each other, the length of the guide groove 203 extending along the axial direction of the connecting pipe 4 is greater than the sum of the distances between the guide block 202 and the sealing block 206 in the axial direction of the sliding pipe 201. This allows the guide block 202 and the sealing block 206 to be simultaneously accommodated in the internal space of the guide groove 203 when the sliding pipe 201 is fully inserted and locked. In addition, a sealing ring 204 is fitted on the outer wall of the sliding pipe 201. The sealing ring 204 is located between the slot 304 and the opening of the connecting pipe 4. The outer wall of the sealing ring 204 is connected to the inner wall of the connecting pipe 4 by an interference fit, thereby forming the first pre-sealing defense line before the fluid reaches the sealing ring 205.

[0035] As another preferred embodiment, in order to improve the convenience of manual operation and the stability of locking, the outer surface of the rotating knob 301 fixedly connected to the threaded post 302 at one end outside the connecting tube 4 is provided with knurled or striped anti-slip texture. The locking components 3 are evenly distributed in three or four sets along the circumference of the connecting tube 4. Correspondingly, the opening position of the slot 304 on the sliding tube 201 corresponds one-to-one with the distribution position of the locking components 3. The sliding tube 201 is firmly locked on the central axis of the connecting tube 4 by multi-point synchronous force application.

[0036] Working principle: When connecting and installing the evaporation separation chamber 1 and the heating chamber 5, the operator first inserts the sliding tube 201 into the opening of the inner wall of the connecting tube 4. By adjusting the angle, the guide block 202 on the outer wall of the sliding tube 201 is aligned with the guide groove 203 on the inner wall of the connecting tube 4. Then, the sliding tube 201 is pushed to slide axially into the connecting tube 4. The sliding engagement of the guide block 202 in the guide groove 203 restricts the circumferential rotation of the sliding tube 201, ensuring that the sliding tube 201 moves along a predetermined straight trajectory, thereby ensuring that the slot 304 on the sliding tube 201 can be accurately aligned with the locking component 3 on the connecting tube 4.

[0037] As the sliding tube 201 slides deeper into the inner wall of the connecting tube 4, the sealing ring 204 on the sliding tube 201 first contacts the inner wall of the connecting tube 4 and establishes the first interference seal. Then, the sealing ring 205 slides to the inner wall area of ​​the connecting tube 4, and at the same time, the sealing block 206 fixed on the sealing ring 205 slides into the internal space of the guide groove 203. The sealing block 206 fills the groove of the guide groove 203. With the sealing ring 205 fitting against the inner wall of the connecting tube 4, a complete seal is achieved at the connection and the guide structure, effectively preventing fluid leakage from the guide groove 203.

[0038] When the sliding tube 201 moves to a predetermined depth so that the slot 304 on the sliding tube 201 aligns with the block 303 on the connecting tube 4, the rotating knob 301 is turned clockwise. The rotating knob 301 drives the threaded column 302 to rotate in the threaded hole of the connecting tube 4 and feed towards the center. The threaded column 302 pushes the block 303, which is rotatably connected to the threaded column 302, to move radially, so that the block 303 is smoothly embedded in the inside of the slot 304. When the block 303 is completely inside the slot 304, the sliding tube 201 is axially fixed inside the connecting tube 4, thus completing the stable connection between the evaporation separation chamber 1 and the heating chamber 5.

[0039] When maintenance or cleaning of the equipment is required, the operator turns the rotary knob 301 counterclockwise. The threaded column 302 drives the locking block 303 to move radially outward and exit the slot 304, releasing the locking state of the sliding tube 201. At this time, the sliding tube 201 can be pulled outward to remove it from the connecting tube 4, thereby realizing the rapid separation of the evaporation separation chamber 1 and the heating chamber 5, which facilitates independent maintenance of each module.
